Which of the following statements is/are true about proteins and amino...
Statement (a) is correct as usually the membrane spanning region of an integral membrane protein is 20-25 amino acid long.
Statement (b) is incorrect, because glycine is the only amino acid which is optically inactive as it has no chiral centre. All other amino acids have atleast one chiral centre, so all other amino acids except glycine are optically active.
Statement (c) is correct as lysine and leucine are the only two amino acids which are exclusively ketogenic in nature.
Statement (d) in incorrect as there are only five amino acids which are both glucogenic and ketogenic in nature. They are tyrosine, isoleucine, phenylalanine, tryptophan and threonine.
Statement (b) is incorrect, because glycine is the only amino acid which is optically inactive as it has no chiral centre. All other amino acids have atleast one chiral centre, so all other amino acids except glycine are optically active.
Statement (c) is correct as lysine and leucine are the only two amino acids which are exclusively ketogenic in nature.
Statement (d) in incorrect as there are only five amino acids which are both glucogenic and ketogenic in nature. They are tyrosine, isoleucine, phenylalanine, tryptophan and threonine.
