Meat is a good source of protein. There are nine essential amino acids which are required under special conditions like illness.
These are- Histidine, Leucine, Isoleucine, Valine, Threonine, Methionine, Lysine, Phenylalanine and Tryptophan. They cannot be synthesized by the body and therefore need to be taken from external protein sources.
Since meat contains all the essential amino acids, therefore it is considered as a good source of protein. Hence, the given statement is false.

Many proteins contain both alpha helices and beta sheets, but some contain just one type of secondary structure.
