DIAAS of pea protein ?5 answersThe Digestible Indispensable Amino Acid Score (DIAAS) of pea protein is reported to be 0.88 without supplementation and can be increased to 1.10 with methionine (Met) supplementation, which is comparable to casein protein. Pea protein is highly digestible in rats, with a true caecal amino acid digestibility of 94%. Pea protein's functional properties can be enhanced through modifications, expanding its applications in various food products. Pea protein and its hydrolysates exhibit health benefits and possess functional properties like solubility, emulsification, and gelling, making them valuable ingredients in the food industry. The DIAAS values of vegetarian dishes, which often include pea protein, were found to be lower compared to meat dishes, emphasizing the importance of protein quality in different food options.
What is the natural unstaurated/saturated lipids composition in cell membrane?4 answersThe composition of natural cell membranes includes a variety of lipids with both saturated and unsaturated fatty acyl chains. Recent studies emphasize the significance of the detailed fatty acyl chain composition in influencing various membrane-related processes, such as oligomerization of transmembrane helices and membrane alignment of certain peptides. Unsaturated fatty acids, like polyunsaturated fatty acids (PUFAs), play a crucial role in membrane organization and function, impacting health differently than trans fatty acids (TFAs). The unsaturation level of acyl chains affects membrane permeation and diffusion, with higher unsaturation leading to lower free energy barriers for molecule transversal diffusion across membranes. Overall, the balance between saturated and unsaturated lipids in cell membranes is essential for maintaining membrane fluidity and functionality.
What are lipids made up of?5 answersLipids are composed of fatty acids (FAs) and other substances such as alcohols, phosphoric acid, and carbohydrates. Fatty acids are monocarboxylic organic acids with a linear carbon chain of 4-26 carbon atoms. They can be saturated or unsaturated and have various properties such as poor water solubility, variable melting and boiling temperatures, and the ability to form soaps and esters. Lipids are classified into simple lipids, which include acylglycerols and waxes, and complex lipids, which include phospholipids, glycolipids, and lipoproteins. Simple lipids are esters of glycerol and fatty acids, while complex lipids are composed of an alcohol, fatty acids, and other components. Lipids also include substances such as terpenes and sterols, which have various structures and functions.
Which fatty acids are good in the diet?4 answersOmega-3 fatty acids, specifically polyunsaturated fatty acids (PUFAs), are considered good in the diet. They have been shown to have overall positive effects on human health, reducing inflammation and markers associated with certain diseases. Omega-3 fatty acids can be obtained from plant seeds and fish, such as in fish oil supplements. Monounsaturated fatty acids (MUFAs) are also beneficial and are found in sources like olive oil. On the other hand, saturated fatty acids and trans fats are associated with an increased risk of coronary heart disease and should be avoided. It is important to note that the consumption of omega-6 fatty acids, like linoleic acid and arachidonic acid, should be balanced with the consumption of long chain omega-3 fatty acids.
What is the lipid content in cacao beans?5 answersCacao beans have a lipid content ranging from approximately 31% to 50% of their dry weight. The lipid fraction of cocoa beans is mainly composed of neutral lipids, with triglyceride molecules being the predominant component. The major fatty acids found in cacao beans are palmitic, oleic, and linoleic acids. The lipid content of cocoa beans is higher in immature beans compared to mature ripe beans. Additionally, the lipid content of dry and roasted cocoa beans, known as cocoa beans after fermentation, is high, with levels reaching up to 31%.
