This 'globin fold' typically consists of eight alpha helices, although some proteins have additional helix extensions at their termini. [4] Since the globin fold contains only helices, it is classified as an all-alpha protein fold. The globin fold is found in its namesake globin families as well as in phycocyanins. The globin fold was thus the ...

The amino acid sequences of the globin subunits usually differ between species, with the difference growing with evolutionary distance. For example, the most common hemoglobin sequences in humans, bonobos and chimpanzees are completely identical, with exactly the same alpha and beta globin protein chains.
This chart provides audio examples for phonetic vowel symbols. The symbols shown include those in the International Phonetic Alphabet (IPA) and added material. The chart is based on the official IPA vowel chart. [1] The International Phonetic Alphabet is an alphabetic system of phonetic notation based primarily on the Latin alphabet.
Schematic representation of a protein electrophoresis gel. All globulins fall into one of the following three categories : Alpha globulins; Beta globulins; Gamma globulins (one group of gamma globulins is the immunoglobulins, which are also known as "antibodies")
The official chart of the IPA, revised in 2020. The International Phonetic Alphabet (IPA) is an alphabetic system of phonetic notation based primarily on the Latin script.It was devised by the International Phonetic Association in the late 19th century as a standard written representation for the sounds of speech.

This key represents diaphonemes, abstractions of speech sounds that accommodate General American, British Received Pronunciation (RP) and to a large extent also Australian, Canadian, Irish (including Ulster), New Zealand, Scottish, South African and Welsh English pronunciations. Therefore, not all of the distinctions shown here are relevant to ...
The following are the non-pulmonic consonants.They are sounds whose airflow is not dependent on the lungs. These include clicks (found in the Khoisan languages and some neighboring Bantu languages of Africa), implosives (found in languages such as Sindhi, Hausa, Swahili and Vietnamese), and ejectives (found in many Amerindian and Caucasian languages).
