(iv)Given that the whey protein powder contributes 20 % of the total daily energy intake of the marathoner, calculate the amount of energy contributed by his other food sources.[1](v)Suggest a simple chemical test to distinguish between phenylalanine and threonine.Describe your observations.NH2...
4 Proteins are an important component of the human diet. Protein molecules are digested and the products of digestion are absorbed into the blood.(a)(i)State one principal source of protein in the diet.[1](ii)Describe the chemical digestion of proteins in named parts of the alimentary canal...
amino acids. The primary structure sequence of amino acids is specified by the gene. In the secondary structure, portions of protein begin to coil fold unique three-dimensional formation. Two kinds of secondary structure units are the a-helix and b-ple 蛋白质是从同一套修建的聚合物20不同...
Note: The possible reasons that the actual band size differs from the predicted are as follows: 1. Splice variants: Alternative splicing may create different sized proteins from the same gene. 2. Relative charge: The composition of amino acids may affects the charge of the protein. ...
Intrinsically disordered proteins and protein regions (IDPs) are prevalent in all proteomes and are essential to cellular function. Unlike folded proteins, IDPs exist in an ensemble of dissimilar conformations. Despite this structural plasticity, intramo
DNA–protein crosslinks (DPCs) induced by aldehydes interfere with replication and transcription. Hereditary deficiencies in DPC repair and aldehyde clearance processes cause progeria, including Ruijs–Aalfs syndrome (RJALS) and AMeD syndrome (AMeDS) in humans. Although the elimination of DPC during re...
Compared to fresh pollen, the stored pollen has less complex polysaccharides (e.g. absence of starch), elevated simple sugars, and altered profiles of amino acids, proteins, and lipids19,22,23,24. Nurse bees consume the pollen, stimulating the development and protein content of larval food-...
Protein is composed of amino acids. It can help the body to receive the nutrients and essential reactions. It can be divided into three types. They can be named as: Essential amino acids. Non-essential amino acids. Conditional amino acids....
ainterests are searching online and treavlling,and i am good at communication 兴趣在网上搜寻并且treavlling,并且我在通信上是好[translate] aThis probably means that free amino acids are used for protein synthesis, 这大概意味着游离氨基酸为蛋白质综合使用,[translate]...
aProteins are from approximately twenty food elements called "amino-acids",which are found more abundantly in animal protein than in vegetable protein. 蛋白质是从大约称“氨基酸的”二十个食物元素,在动物蛋白质中被找到非常比在菜蛋白质。[translate]...
